What is the difference between a community and a population?

• A community is all of the population in a particular area; and population is the members of a specier that live in the same area
• A community is the members of a species that live in the same area; and population is the members of a speicies that live in the same area

What is the difference between a ecosystem and biosphere?

• An ecosystem is the Earth and all of its orgaisms and environments; and a bioshpere is all living things and their physical environments within a particular area
• An ecosystem is all living things and their physical environments within a particular area; and a bioshpere is the Earth and all of its orgaisms and environments.

What is the difference beween abiotic factors and biotic factors

• An abiotic factor is any part of an ecosystem that has never been living, and a biotic factor is any part of an ecosystem that is living or used to be living.
• An abiotic factor is any part of an ecosystem that is living or used to be living, and a biotic factor is any part of an ecosystem that has never been living

What is the difference between population population size and population density

• None of these are correct
• population size is the number of individuals in a population per unit of are, and population density is the number of individual organisms present in a population at a given time
• Population size is the number of individual organisms present in a population at a given time; and population density is the number of individuals in a population per unit of are.
